My Sapphire 7950 is still throwing up driver crashes at 1080 core all the way up to 1250v??? WTF, it will do 1070 on stock but wont budge from there even with more volts?

That is really odd. Have you tried something like furmark on 1070? If it comes to the point that you have no idea, I would check long term stability on 1070. If it survives, it looks like it may be a poorly fabricated chip.

I more or less have the same Video card you do. I will do 1070 and up this friday or saturday and post my results.

All part of the silicon gamble from what I understand, mine has artifacts if I go past 1125 core. So I leave it at 1100.

Though I have read some people getting 1300 with this same card... so yeah silicon gamble is all.

OK, update, my core clock seems to be affected directly by my memory clock, which I didn't think was the case, however in benching some more I have realised that lowering the seemingly stable mem speed of 1575 directly affects what I can OC on the core, I thought they were seperate entities these days?

So to cut a long message short, I have broken 1100 core by reducing my vram to stock 1250 and am now at 1140 on the core, also seems stable with mem at 1400 at that core speed. I am slowly raising both to find an equilibrium and will be back, endless runs of 3dMark11........ YAY

Just a suggestion and I have no authority. I have your thread subscribed because I find it interesting. I get an email everytime someone post. That is why I made the suggestion. Guess I will just unsubscribe and not pay attention.

I know you don't, hence I said maybe a PM might be the better way to go, I am sorry I double posted, though posts were relevant and making different posts with different findings as editing doesn't always have the desired effect. Hope you have enjoyed the bulk of the comments, am at 10K with 1200 core

All this talk of overclocking 79xx has started me thinking if finally pushin my cards and see what they can do. They're comfortably sitting at 1050/1500 now, but that's not nearly good enough right?

As soon as my wife gets off my PC (looking for crap on Craigslist; she has a phone and a laptop, but needs my pc ), I'm going to reinstall 12.11 and start pushing my cards, hopefully with good numbers.
